Principle open/attic blowing

Open/attic blowing

Open or attic blowing is done on an open floor/space. The ceiling of a house is often insulated in that way.

Open/attic blowing without added moisture
The fill spreading can be done with a hose or a stiff pipe.

Open/attic blowing with added moisture
Wind-blown dispersal of the insulation material can be avoided by following spreading of moisture on the surface of the material. Thereby the insulation material pastes over because of the adhesive agents in itself.
Another option is fill spreading with moisture addition. This has several advantages. On the one hand, the dust emission is reduced significantly and the targeting on far-out areas can be controlled better. Lastly, the continuous adhesion of the material lets you neglect the overfilling which is normally necessary because of settlement.
